2011 Winter Project Week:MIDAS for data hosting

Key Investigators

Make use of the MIDAS data archiving system to host data related to tests such as baseline and comparison images.

Motivation:

Not all users will want to build and test every module of Slicer, so they shouldn't have to download the testing data for every part of Slicer
Encourage the optional use of testing with "large" datasets that aren't downloaded unless the "large-data" tests are configured to run
Don't download any duplicated test data more than once

MIDAS+CTest: create a thin wrapper for "add_test" calls that will allow for adding a test that references remote data on a MIDAS server in a human-readable way
The underlying mechanism will address data by its checksum to ensure integrity and no duplication of downloads, but test creators and users shouldn't have to deal with checksums
Create an "Easy Upload" page for the Slicer community to allow test data to be uploaded and ready to test against with as few clicks as possible
MIDASDesktop: A GUI application for moving data between a client machine and a MIDAS server

MIDAS+CTest macro has been created and is currently in use successfully with the BRAINSTools test data.
Easy Upload page has a working prototype and requires further improvements and customization for Slicer
MIDASDesktop: svn repo is here https://www.kitware.com/svn/KWPublic/trunk/MIDAS/MIDAScpp

Test data will be hosted publicly (with any necessary access control) on midas.kitware.com
Test data in the Slicer4 repository will be replaced by a reference
That site will also host the Slicer Easy Upload page.
